29045	admin CSS overrides Select/SelectMultiple size attribute	Jonah Bishop	Jonah Bishop	"I have an admin page set up for a model like so:

{{{
@admin.register(p_models.ScheduleType)
class ScheduleTypeAdmin(admin.ModelAdmin):
    formfield_overrides = {
        models.ManyToManyField: {'widget': forms.SelectMultiple(attrs={'size': '30'})},
    }

    list_display = ('name',)
}}}

The resulting ManyToMany field has the **size** attribute set properly, but every browser I try only shows about 8 rows (not 30, as I instructed). I've cleared cache, and tried in multiple browsers (Chrome 63, Firefox 57). My site uses Django 1.11.9.

It looks like the CSS style rules are overriding the **size** attribute. I'm guessing adding a **height: auto;** rule to the **select[multiple]** style set would fix it (it appears to do so in Chrome, at least)."	Bug	closed	contrib.admin	1.11	Normal	fixed		elky	Accepted	1	0	0	0	0	0
